I'm back again to ask, can one replace the vented oil cap filler at the front of the engine.

There seems to be a little bit of smoke escaping... Last summer I removed completely the revers gearbox cover that had a spout with a vented cap and replaced it with a solid cover plate. No adverse effects other than a cleaner breathable air in the cabin.

The cabin is a lot more pleasurable, now that there is no plumes of smoke in the inner cabin nor engine compartment to set off the Co2 sensor on board.

My question is what would happen if I remove the vented oil cap... Same one that was on my gearbox cover.??
